Good point about the various air routes. It is an intrinsic part of our way of working which is one reason I think those big planes are so critical.
You reminded me of something. We don't have very many shipyards. If something like this ever got started, please God don't let it, a lot of ships would be sunk and need to be replaced. They may be able to do that more easily than we.
I thought about mentioning Korea but let it go for the reason you said, airplanes might be too easy to stop and you would be better off with lots of small ships making the passage.
